To a/ZZ whom it may concern: 5

Be it known that I, ERIK GUs'rAE NIooLAUs SALENIUS, a subjectof the Kingof Sweden and Norway, and a resident of Albano, in the Kingdom ofSweden, have invented certain new and useful Improvements in CentrifugalVessels or Drums, of which the following is a specication.

This invention relates to the drums or vessels used in centrifugalmachines; and the object of the invention is to improve the constructionof vessels of this class which have interiorly-arranged rings carryingconical deilecting-plates.

An embodiment of the invention is illustratedin the accompanyingdrawings, where- 1n- Figure l is a vertical axial section of acentrifugal vessel embodying my improvements; and Fig. 2 is a horizontalsection of the same, taken just above the bottom thereof. Fig. 3 is anenlarged sectional detail View of one of the rings, illustrating themanner of supplying one ring with more than one conical plate.

In carrying out'my invention in its preferred form I employ a cylinderor drum 01 which is relatively thin and of substantiallyuniformthickness from bottom to top, said drum having at its top an inturnedange or lug to receive screws f and a bayonet-fastening at the bottom,Fig. 2, for securing in it the removable bottom e. cover d, thering-ange of which takes under The drum a may be inverted, the cover dput in place, then a series of rings b .put in place, which extend theentire depth of the drum from cover to bottom, then the bottom e pnt inplace and secured, and finally the screws f may be driven down or inupon the ringiiange of the cover d, so as to press the rings h tightlytogether. The superposed rings ZJ fit snugly within the drumoJ and havebetween them, as also between the terminal rings and the bottom e andcover d, packingrings c, of suitable material to form tight joints. Oneach ring b is a deflecting-plate g of a known conical form, and in theplate g, adjacent to the point where it springs from the ring b, areapertures h for the upward flow of the skim-milk to the outlet-pipe 't'.Obviously each ring b may carry more than one plate g, as seen in Fig.3, which shows This drum has a two concavo-convex plates on one ring.This construction provides an inner wall to the drum a made up of therings b and reinforcing the outer wall of the drum, which may berelatively quite thin. The advantage of the construction resides in thefact that the inner wall of rings resists the internal pres- 6o sure andis economical to construct, While the wall of the drum proper, a, may bemade much thinner than usual, and consequently at much less cost.

Having thus described my invention, I claiml. In a centrifugal vessel,the combination with a relatively-thin outer drum a, of uniformthickness from top to bottom, of aseries of rings b which fit into saiddrum and are 7o superposed, extending from the bottom to the cover ofthe drum and forming an inner reinforcing-wall therefor, the plates g onsaid rings, packing between said rings, and means for pressing the ringsb firmly together, substantially as set forth.

2. In a centrifugal vessel, the combination with the relatively-thindrum a., having a wall of substantially-uniform thickness from top tobottom, of the rings l), tting into said 8o drum and superposed, theplates g on said rings, the packing c between said rings, the cover d,having a ring-ilange which rests on the top ring l), and theclamping-screws f, which are driven down through inturned iianges on thedrum onto said ring-hangs of the cover, substantially as set forth.

3. In a centrifugal vessel, the combination with a relatively-thin drumct, of substantiallyuniform thickness from top t0 bottom, and 9o havinginturned flanges at its top to receive the screws f, the said screws,the cover d, and the removable bottom e, of the series of rings b,superposed within the drum and extending therein from the bottom to thecover so as to form a reinforcing-wall for the drum, and the plates g,carried by said rings, substantially as set forth.

In witness whereof I have hereunto signed my name in the presence of twosubscribing 10o witness es.
